Water scarcity in Iran

Water scarcity in Iran is caused by high climatic variability, uneven distribution of water, over exploitation of available water resources,and prioritization of economic development. Water scarcity in Iran is further exacerbated by climate change.

Water scarcity can be a result of two mechanisms: physical (absolute) water scarcity and economic water scarcity, where physical water scarcity is a result of inadequate natural water resources to supply a region's demand, and economic water scarcity is a result of poor management of the sufficient available water resources.

Rainfall is highly seasonal, which led to the government building dams to ensure a more consistent water supply. Despite this, water availability has declined since the 20th century whilst demand has increased. By the 2010s, authorities and the United Nations were describing it as a crisis and it contributed to protests in the country.
